UnityWebRequestTexture returns magenta in build

Hi.

I'm using unity www functions to load image files from harddrive as texture2D. But somehow is not working in release build. In Editor works fine, image is loaded to texture. But in build I see online magenta color instead of image. There is no errors in log file.

Unity version 2018.3.0b6
Script Runtime Version: .NET 4.x Equivalent
Scripting Backend: Mono
Api Compatibility Level: .NET 4.x

This is what I have in coroutine

Code (CSharp):

1. var req = UnityEngine.Networking.UnityWebRequestTexture.GetTexture(file);
2.         yield return req.SendWebRequest();
3.         onDone(UnityEngine.Networking.DownloadHandlerTexture.GetContent(req));
4.  

onDone is property

Code (CSharp):

1. Action<Texture2D> onDone;

Can somebody help me? What can be possible wrong?

 

magenta = broken shader

 

Man, you are Boss. It was because of it, I needed to add shader to "always included shaders" in Graphics settings.
